SmartWay/CARB

The U.S. Environmental Protection Agency’s SmartWay Transport Partnership was launched in 2004 and is a voluntary program between the U.S. government and the freight transportation industry to reduce the industry’s fuel consumption and greenhouse gas emissions.

The SmartWay Technology program develops test protocols and verifies the performance of vehicles, technologies and equipment that have the potential to reduce greenhouse gases and other air pollutants from freight transport operations. The program establishes credible performance criteria and reviews test data to ensure that vehicles, equipment and technologies certified or verified by the program will help fleets improve their fuel efficiency and reduce emissions.

Original Equipment Manufacturer (OEM) tractors and trailers can obtain “SmartWay Certified” status, while vehicle components, such as aerodynamic devices, can qualify for listing as “U.S. EPA Verified Technologies”, sometimes referred to as SmartWay approved technologies. Verification requires that components be tested in accordance with a modified version of SAE J1321 test protocol.

Aerodynamic devices that qualify as U.S. EPA Verified Technologies are divided into categories based on the part of the trailer they address and the extent of their third party tested fuel savings. The two categories that feature the highest estimated fuel savings, of at least 5%, are ADVANCED TRAILER SKIRTS andADVANCED TRAILER END FAIRINGS.

ATDYNAMICS TRAILERTAIL® 4×4 and TRIDENT meet the ADVANCED TRAILER END FAIRING criteria for a minimum of 5% fuel savings and the ATDYNAMICS ECOSKIRT® meets the ADVANCED TRAILER SKIRTqualifications with greater than 5% fuel savings.

The California Air Resources Board (CARB) has adopted the Heavy-Duty Vehicle Greenhouse Gas Emission Reduction Regulation to improve the fuel efficiency of the heavy-duty tractor and 53 foot trailer combination through the implementation of tractor and trailer aerodynamics and low rolling-resistance tires.

ATDynamics provides trucking fleets with technology solutions to meet or exceed the trailer aerodynamic requirements of the CARB regulations at a profit. For fleets that own both trucks and trailers, ATDynamics aerodynamic equipment investments typically have a 6-24 month payback period and a 50-200% annual return. For fleets owning trailers but utilizing owner-operated trucks, equipment payback is realized through shared savings models and improved driver retention and recruitment.

TRAILERTAIL® TECHNOLOGY IS THE ONLY STAND-ALONE REAR-DRAG AERODYNAMICS TECHNOLOGY IN THE INDUSTRY which fully complies with CARB aerodynamics regulations given its SmartWay verified 5.54% fuel savings at 65 mph for TrailerTail® 4×4 and 5.09% at 65 mph for Trident.

Optimizing trailer aerodynamics has become a critical cost and competitive advantage for fleets pulling trailers over 25,000 miles per year at highway speed. Fleets operating AeroTrailers™ (trailers equipped with TrailerTails® and trailer skirts) burn 8-12% less fuel than traditional trailers, adding approximately 6 cents more profit per mile to a trucking company’s bottom line.
